'piete 32 secured g the electricity thereto by means of a bolt 33, which wear plate has a boss 34- to form a centering device for the pulsator runner 35. The pulsator runner has a channel 36 extending part Way around its face and it has a portion 37 which rubs on the wear plate 32, a small hole 2 8 being provided to break the vacuum on the pipe 527 once during each rotation of the runner and a hole 39'being provided in the casing 25 to allow the air to have access to the runner.

A small pipe i0 on which is mounted a gage 41 is connected with the pipe 27 to show the operating conditions of the apparatus.

`The vacuum receptacle has a pipe 42 ein.

tending out oi' the bottom thereof and connected with the pump 10, said pump being of any well known form of the so-called rotary pressure blowers. The vacuum pipe and vacuum chamber are connected to the lpump by means of a clamp 4-3 and hand screw all, While the cover i5 of the vacuum receptacle is secured to the receptacle 3l by means oi the clamp 46 and hand screw a7.

Extending away from the pump casing is a pipe 48 which may either be led into the milk can 49 or may be connected with a suitable pipe line leading toa place of dis* charge for the milk as may be desired.

The pipe 27 has a connection 50 thereon with branches T1 and 52 to which the tubes 53 and 54 extending to the milking cups 1( are placed. The cover 45 of the vacuum chamber 1s provided with a plug 56 having a cover 57 thereon and having a valve 58 mounted on a stem 59 extending through said plug, a spring 60 being used to regulate the pressure Within the vacuum chamber, it being well known in the art that to prevent injuring the cows the pressures used must be controlled Within narrow limits.

The operation of the apparatus-is as follows: The can and machine being placed in a convenient location, the motor is started and the teat cups are then placed on the cowsl teats. As the motor operates the pump the pulsator runner rotates at a much lower rate of speed because of the Worm gear driving it and each time the opening 38 passes the end of the pipe 27 it releases the vacuum in the tubes 53 and 54 thereby giv ing the necessary pulsating effect to milk the cows, While as the milk is drawn from the cows it passes tlnfough the vacuum chamber and pump and is delivered into the cans.

An especial advantage ot' this machine lies in the fact that the milk passes through the pump, thereby always keeping the pump properly primed so that no trouble is had in maintaining the necessary vacuum, the pump serving the double purpose of handling the milk and maintaining the vacuum.

Having thus described my invention what l claim as new and desire to secure by Letters latent orl the United States, is as follows, modifications Within the scope of the claims being expressly reserved:

l. A milking machine comprising a base, a motor thereon, a pump connected with the motor, a vacuum chamber adjacent the um) a nxlsator casin su 'i )orted on the.

base, a pulsator in said casing, a pipe extending from the pulsator casing to the vacuum chamber, vacuum milking cups, a tube extending from the milking cups to the pulsator casing, the milk from the milking cups passing through the pulsator, vacuum chamber and pump, and a discharge pipe extending from said pump to a suitable receptacle for the milk.

2. A. milking machine comprising a base, a motor thereon, an air pumpoperated by the motor, a pulsator casing, a rotary pulsator therein adapted to break the vacuum intermittently, a pipe extending from said pulsator casing to a series of vacuum milking cups, a vacuum chamber, a pipe connecting the pulsator casing and vacuum chamber, a pipe connecting the vacuum chamber and pump, a discharge pipe extending from the pump to a suitable receptacle for the milk, the pulsator casing having an opening whereby the vacuum in. the milking cups may be broken Without breaking the vacuum in the pipe leading to the vacuum chamber.

8. A milking machine comprising a base, a motor thereon, a pump operated by the motor and directly connected therewith, a vacuum chamber connected with the pump, an inwardly opening valve to determine the pressure Within the vacuum chamber, a pulsat-or casing, a pipe connecting the pulsator casing and vacuum chamber, a revoluble pulsator Within the easing having an opening therethrough to break the Vacuum in the pipe to which the milking tubes are to be connected Without breaking the vacuum in the vacuum chamber, mechanical means to rotate said pulsator, a series oil milking cups having suitable pipe connections with the pulsator, and a discharge pipe connected with the pump Jor discharging the milk into a suitable receptacle.

4. A milking machine comprising a base having a motor thereon, a vacuum pump operated by said motor, a Vvacuum chamber connected wit he pump, a p'ulsator casing, milking cups, a tube extending from the milking cups to the pulsator casing, a pipe vextendingfrom. the pulsator casing to the vacuum chamber, and a mechanically oper-v ated rotary disk in the pulsator casing having a channel to deliver the milk from the milking cups to the vacuum chamber and also having an opening therein to break the
